Hi All,
I have two models (User and Event) with multiple has_many through
associations, where my current association is by the below logic:
1. User can participate in many events through EventGroup
2. Event has many users through EventGroup
3. User can like many events through Eventgroup
4. Event has many user likes through Eventgroup
*Model:*
class User
has_many :event_groups
has_many :events,:through => :event_groups
has_many :event_likes,:through => :event_groups,:class_name =>
"Event"end
class Event
has_many :event_groups
has_many :users,:through => :event_groups
has_many :user_likes,:through => :event_groups,:class_name =>
"User"end
class EventGroup
belongs_to :user
belongs_to :event
belongs_to :user_like,:class_name => "User"
belongs_to :event_like,:class_name => "Event"end
*EventGroup columns:*
user_id
event_id
user_like_id
event_like_id
After setting up the association I tried to create the association
record
with the below code:
user = User.first
user.event_likes << Event.first
user.save
This is working fine and I can able to get the events liked by that
user
as user.event_likes.
But I am not able to get the User records by *event.user_likes*, so I
checked my eventgroup record. It has the nil value for user_like_id.
#<EventGroup id: 24, event_id: 1, user_id: 2,event_like_id: 1,
user_like_id: nil>
Let me know the proper way to do this.
